LC-37D4U TV sharp aquos

NO SOUND...at all. None on DVD either. Dishnet says problem is in TV. Everyone seems to agree. Burnt fuse on inverter board has been suggested. Was referred to a repair place. They laughed at the burnt fuse idea. Looks like a $500 more or less fix according to servicement. any ideas?

Same problem. NO sound no matter what type of device I use. DVD, Dish DVR. Have an extended warranty but it is like pulling teeth to get anyone to return my calls to set up an appt to come and repair it. I think I could probably fix it my self if I knew what the part was called that needed to be replaced, Any idea what the part number might be?Same problem.

We have frequent outages causing the TV to turn on from standby mode when power returns. (These ..... Sharp LC-70LE650U 70-Inch Aquos TV TURNS ON WITH PERFECT PICTURE AND ..... It has thin horizontal lines on the top quarter of thescreen. ..... hey there, bought a 52lg60-ua had no image/picture but had sound.

You could open up the TV and look for signs of burnt components then try to replace the components or try to find a replacement for the entire affected board on ebay or something. If you can find out what the problem is maybe the service person will lower there price. $600 does seem very steap, it should be something closer to $60 an hour with maybe the first $60 as an estimate.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.http://en.wikipedia.org/wiki/Capacitor_plaguePlease post back what you find.

Almost all intermittent audio or audio failure problems with Sharp Aquos LC**D4U, LC**D5U, LC**D6U, and LC**D7U televisions are the result of a relatively simple design flaw involving the heatsink pad compound used on the Tripath TA-2024 amplifier chip (IC2502) found on the A/V board.This compound has a fairly low melting point and, over time, tends to seep out from between both top and bottom heatsinks onto the legs of this chip as well as onto circuitry immediately surrounding it.Further, over time the seeping compound also becomes somewhat conductive creating bridges which short the audio amplifier circuit causing everything from intermittent audio to complete audio failure.Fortunately, in almost every case audio can be completely restored by cleaning the old compound from both top/bottom heatsinks and from both sides of the PC board in the area immediately surrounding the chip (I used rubbing alcohol which worked quite well).Sharp has issued a service bulletin addressing this issue (LCDTV-194) wherein a ‘2502 Heat Kit’ is specified.This kit is Sharp Part Number: PSPKIT663WJZZ and is available from circuitcity.partsearch.com for $19.95.However, it’s entirely possible to get by with the heat pad only, Sharp Part Number: PSPAZA663WJKZ for only $9.95.Please note that board replacement for this problem is almost never necessary, so if you’re working with a repair technician be sure and insist that he/she be certain to try cleaning the old board and replacing the aforementioned heatsink pads before charging you for a new board.If one is reasonably familiar with electronics disassembly/reassembly and is willing to take their time, this can even be a DIY project.It is possible to find ‘important service references’ by simply entering LC26D4U (the 5, 6, and 7 series are very similar, and this information covers all screen sizes) into the search field at eserviceinfo.com.This will greatly aid in disassembly/reassembly of the TV, as the A/V board is somewhat ‘buried’ under other boards.Please refer to post # 373 at avsforum.com/avs-vb/showthread.php?t=647174&page=13 for pics of the information detailed here.Particular thanks are owed ‘Aureius’ of the AVS forums for his research efforts concerning this issue !

Is this a problem that just started or has been since you bought the TV ..Try going into the control pannel and checking your sound settings. Make sure it is not set to something diffrent on MTS (Mulit-channel Television Sound)Some times the sound gets switched while programing your TV. Make sure it is not turned on to SAP (this sometimes will happen and you will get NO audio) There should be several settings on these tvs for your audio ..Check to see if the "variable " is selected in "output select ". Also check to make sure your plugs to the outputs are correctly installed and if you have it hooked up to a home theater try turning it on , you may also wish to try to change the settings IE , tv , DVD , VCR ect on the home theater as sometimes they get pluged into the wrong input . If all else fails I would return it to place of purchace or call thier tech support at Sharp , ask for a supervisor ...

I have the same model TV that is 18 months old. The repairman wanted $365.00 to replace the inverter and update something on it. From what I have seen online, it is mainly just loose screws on the inverter. I called Sharp and they are paying for the repair on the TV
